2 Claims.

This invention relates particularly to mattresses and to the manufacturethereof; and the primary object is to provide for improved tufting ofmattresses with the tufting cord or tape concealed 5 from view.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a. broken sectional view of a mattress tufted in accordancewith my invention; Fig. 2, a

sectional view in elevation similar to Fig. 1, showing diagrammaticallythe method of tying; Fig. 3, a broken plan view of the mattress; Fig. 4,a broken perspective view of the tie member secured to one side of themattress casing; Fig. 5, a sectional view, the section being taken asindicated at line 5 of Fig. 4; Fig. 6, a perspective view of a tiemember secured to an opposite side of the mattress casing; Fig. 'l, aview of the tie member shown in Fig. 4 being tied to the tie membershown in Fig. 6; and Fig. 8 shows the completion of the tying operation.

The invention is shown applied to a mattress having a filling whichcomprises a body of springs and layers of cotton or the like coveringthe springs. However, the invention may be used in connection withmattresses having any Suitable In the illustration given, A designates afilling comprising a spring structure A and layers of cotton or thelike, A overthe spring structure,

and B designates a casing for the mattress.

The spring structure A shown is of the type in which coil springs areencased in fabric cells.

The casing B comprises a top cover 10 and bottom cover 11. The top andbottom co'vers, which cover the broad sides of the mattress, areconnected with the bong or border 13 by means of corner seams 14. Ifdesired, the boxing 13 may be reinforced with quilting etc. 15.

.Ey improved method of tufting mattresses comprises broadly thestitching oi tie members to opposite inner sides of the mattress casing,drawing one of the tie members, by means of a needle, through the bodyof the mattress and tying it to the other tie member.

in the illustration given, a tie member 16 is eyelet stitched to the topcover 10 in such a manner that a loop 17 is formed. As shown moreclearly in Fig. e, the free ends of the tie member are brought togetherinto overlapp relation and then secured by eyelet stitching to the cover10. To the inner side of the bottom ooverll at a point opposite to tiemember 16, I prefer to secure a tie member 18 of the shape shown moreclearly in Fig. 6. The single strip of tape or cord is sewed,

1932. Serial No. 584,487

by eyelet stitching, at about its middle point to the inner side ofbottom 11.

In the stitching operation, I prefer to use an eyelet-stitching machinedevised. to accomplish the purpose and preferably a machine of the typedescribed in my c'o-pending application,

. Serial No.- 525,750. While it is unnecessary to and tie member, aswill be understood more 7 clearly from Fig. 5.

The tufting is accomplished, as illustrated more clearly in Figs. 2, 7and 8, by thrusting a long needle 19 provided at its point with an .eyethrough which a portion of the loop 17 is passed, through 7 the fillingor body of the mattress, while the mattress is under compression,passing the needle point through the two legs of tie member 18,withdrawing the needle to free loop'21 and then passing the ends 20 oftape 18 through the loop portion 21 of the member 16 which extendsthrough the tape strips 18. A pull exerted upon the tie member 16 formsa secure knot, as illus= trated in Fig. 8.

In the tufting operation it is preferred to start near the center of themattress and to work each way, the mattress body being placed undercompression along the line where the tufts are being made.

By my improved method, I dispense with metal 99 eyelets and employstitched eyelets which may be formed economically upon the imperioratedfabric, the selected points being simply marked in advance of theeyelet-stitching operation to insure a desired arrangement or patternfor the tufting. At the same time, the cords or tape used in the tuftingoperationare wholly concealed. The tufted mattress is sturdy and uniformin contour.

The foregoing detailed description is given for 1w clearness ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, but the appended claims should be construed as broadly aspermissible, in view of the prior art.

I claim:

1. In the process of mattress manufacture, the steps which includesecuring a tie member in the form of a loop to the inner side oi themattress casing, securing a strip of tape to the inner side of thecasing opposite said first-mentioned tie 110 a strip of tape to theinner side of the casing opposite said first-mentioned tie member,forming a mattress body in said casing, tufting the mattress by stepswhich include thrusting a tufting needle carrying said first-mentionedtie memher through said mattress bodv and also through a free endportion of said tape, and looping the loop-end of said first-mentionedtie member which has passed through said end portion of said tape aboutthe end of said tape member.
